Memphis: Finding and fixing NUMA-related performance problems on multi-core platforms

Abstract

Until recently, most high-end scientific applications have been immune to performance problems caused by Non-Uniform Memory Access (NUMA). However, current trends in microprocessor design are pushing NUMA to smaller and smaller scales. This paper examines the current state of NUMA and makes several contributions. First, we summarize the performance problems… (More)
